VQ647F-16C Pneumatic V-Clamp Ball Valve

Product Overview

The VQ647F-16C Pneumatic V-Clamp Ball Valve is a V-shaped notched ball panel with a rotating shaft at the upper and lower ends of the ball core. It has a sturdy structure, wear-resistant valve material, a DC channel, and a seat with an energy increasing ring to adjust the sealing force. When closed, the V-shaped incision and valve seat generate wedge-shaped shear force, which is widely used in slurry, mud particles, and fiber environments. It is matched with a valve positioner to achieve proportional adjustment, and the control box with a valve can quickly cut off.

Performance Characteristics

• The long neck valve cover structure isolates the packing box from the low-temperature position, ensuring the sealing effect of the packing and making it easier to wrap the insulation material. It has the function of protecting the packing box and preventing the loss of cold energy of the low-temperature valve.
• The gasket used for low-temperature ball valves has reliable sealing and recovery properties at room temperature, low temperature state, and temperature changes.
• When the operating temperature is below -100 ℃, the valve stem material is treated with chrome plating or nitriding to increase the surface hardness of the valve stem and improve the reliability of the packing seal.
• The low-temperature ball valve is designed with a structure to prevent abnormal pressure rise. A pressure relief valve is installed at the inlet end of the valve, which can effectively prevent the pressure in the valve chamber from rising and ensure the safe use of the valve.
• When used in working conditions below -100 ℃, valve parts should undergo cryogenic treatment before precision machining, which involves immersing the parts in a liquid nitrogen tank for cooling.
